The Section for Metal Structures and Transport Devices

The Section performs:

• laboratory tests of metal structures and their elements under static or dynamic, short-term or long-term loadings,
• laboratory tests of mechanical engineering structural elements and assemblages under static or dynamic, instantaneous or random loadings,
• measurements of vibrations,
• loading tests of metal structures,
• assessments of the load-carrying capacity of metal structures (such as bridges, cranes, and crane rails),
• issuing of technical approval documents for metal structures and their elements (industrial buildings, facade substructures and elements, standardized structural elements, support systems).

Other activities include:

• measurements and analyses of loadings in the structural elements and assemblages of mechanical engineering structures (road and rail vehicles, cranes),
• research into the behaviour of mechanical engineering structures and structural elements for design optimization and assessment of safety against dynamic fracture,
• expert studies of the causes of damage to metal structures.

In the field of aerial ropeways and ski-lifts, the Section performs:

• load-carrying capacity tests of wire ropes,
• static and dynamic tests of structural and other elements such as clamps, seats, cabins, hangers, and suspension gear,
• supervision of the installation, socketing and splicing of wire ropes,
• magnetic-inductive field tests of wire ropes,
• testing of newly-constructed aerial ropeways and ski-lifts,
• periodical testing of existing ropeways and ski-lifts and their safety devices,
• expert studies concerning any defects or deficiencies in ropeway or ski-lift equipment.

ZAG Ljubljana has been authorized by the Ministry of Transport and Communications of the Republic of Slovenia to issue technical approval documents for the operation of aerial ropeways and ski-lifts.
